Auxiliary support device for processing large thin-walled components and using method

Abstract

The invention discloses an auxiliary supporting device for processing large thin-wall components and a using method for the auxiliary supporting device. The device comprises a base, an X-direction position regulating unit, a Y-direction position regulating unit and a Z-direction position regulating unit. The using method for the device comprises the following steps of: integrally putting the auxiliary supporting device onto a workbench of a processing machine tool; controlling an electric lifting post to descend, and ensuring a supporting plate to be positioned below a Y-direction platform; putting thin-wall components onto the upper surface of the Y-direction platform, and enabling drilled positions of the thin-wall components to be roughly aligned to the supporting plate; separately controlling an X-direction drive motor and a Y-direction drive motor to rotate to drive an X-direction platform and the Y-direction platform to horizontally move, enabling the drilled positions of the thin-wall components to be fine aligned to the supporting plate, and ensuring the center lines of to-be-processed holes in the thin-wall components to be superposed with the center line of a positioning hole in the supporting plate; positioning and clamping the thin-wall components onto the workbench of the processing machine tool; controlling the electric lifting post to ascend, and ensuring the upper surface of the supporting plate to be in tight fit to the thin-wall components; and starting the processing machine tool to start drilling processing.

Description

technical field

[0001] The invention belongs to the technical field of aerospace parts processing, and in particular relates to an auxiliary supporting device for processing large thin-walled components and a use method thereof. Background technique

[0002] In the field of aerospace, there are a large number of metal or non-metallic large thin-walled components. Limited by their thin-walled structures, large thin-walled components generally have the disadvantage of low stiffness. During the processing of large thin-walled components , must be affected by the cutting force, and the machining deformation and chattering phenomenon will occur under the action of the cutting force.

[0003] At present, the use of large non-metallic thin-walled components is increasing day by day, and the rigidity of non-metallic large thin-walled components is lower than that of metal components, and their processing deformation and chattering are more serious.
